Action of Streptozotocin on Insulin and Glucagon Responses of Rat Islets

Abstract

Experimental diabetes was produced in rats by i.v. streptozotocin injection (65 mg/kg). There was a significant increase in blood glucose and serum glucagon, while there was a significant decrease in serum insulin in diabetic animals as compared with controls. It is of interest that the glucagon elevation in the streptozotocin-induced diabetes in animals is of comparable magnitude to that seen in the ketoacidotic state of human diabetes.
